    • The present invention provides a method and system for handoff in a wireless communication network. In one embodiment, a common handoff encryption key is generated by an authentication server and transmitted to a first access point and a second access point. The first access point transmits the handoff encryption key to a wireless terminal. The wireless terminal encrypts output data with the handoff encryption key. When the wireless terminal is associated with the second access point, the second access point decrypts data from the wireless terminal with the handoff encryption key. In a second embodiment, a handoff WEP key generation secret parameter is provided to a first and a second access point. Both access points generate a handoff WEP key as a function of the handoff WEP key generation secret parameter and an address of a wireless terminal. The first access point transmits the handoff WEP key to the wireless terminal. The second access point communicates data packets encrypted with the handoff WEP key with the wireless terminal.
    • 本发明提供了一种用于无线通信网络中切换的方法和系统。 在一个实施例中,公共切换加密密钥由认证服务器生成并被发送到第一接入点和第二接入点。 第一接入点将切换加密密钥发送到无线终端。 无线终端用切换加密密钥加密输出数据。 当无线终端与第二接入点相关联时,第二接入点利用切换加密密钥从无线终端解密数据。 在第二实施例中,将切换WEP密钥生成秘密参数提供给第一和第二接入点。 两个接入点根据切换WEP密钥生成秘密参数和无线终端的地址生成切换WEP密钥。 第一接入点将切换WEP密钥发送到无线终端。 第二接入点将与切换WEP密钥一起加密的数据分组与无线终端进行通信。
